The present invention relates to wall boards and particularly to animproved fastening device, for securing wall boards in position.

Prior to going into the details of this improved fastening device, it iswell to give a rsum of the extent of use of wall boards.

At first wall boards were used for erecting partitions either in roomsin dwellings or ofiice buildings or the like. A further use of wallboards is in the construction of new dwellings, wherein practically allthe partitions may comprise wall board, and more especially in bungalowtype houses as well as in some relatively inexpensive apartment housesor small ofiices.

Still another advance use involves the construction of corners,exteriorly and interiorly of rooms, therefore with this present invention there is an extensive field-for a practical and improved fasteningdevice. I

The present invention has for its purpose to provide a very inexpensiveand improved form of construction, which will permit of the expansionand contraction of the wall board sections, and yet insure a closedjoint between the sections.

Heretofore in employing wall board a wooden moulding is used forcovering the seam of the wall board sections, the latter being fastenedto the studding, and in this construction there is no way for permittingof expansion and contraction, but there is no practical way of providingfor the proper paint job. In other words the wall board with the woodenmoulding is first fastened to the studding, then the moulding is appliedand subsequently the wall board and moulding are painted.

Consequently as there is expansion and contraction to the wall boardsections the wall board will buckle between the strips of moulding, andin the construction where moulding is used to permit of expansion andcontrac tion of the wall board sections, the wall board sections will socontract as to move relatively to the moulding and expose unpaintedsurfaces of the wall board, presenting a very untidy and undesirableappearance.

It is therefore the purpose of the present ms. Serial m. came-1.

invention to provide an improved fastening devlce for moulding andwallboard sections, such as will permit the moulding and the wall board tobe painted and subsequently the moulding forced on in place. Howeverprior to fastening the moulding home the wall board may be painted underthe moulding, so that when the wall board contracts, no unpaintedsurface of the wall board will be exposed. In other words this inventioninvolves the placing of the molding in one position while the wall boardis being painted, in order to paint under the moulding, and forcing themoulding into a section position subsequently to completing the paintingof the surface of the moulding and wall board.

Another purpose is to provide a moulding first fastened directly to thestudding and not to the wall board or other wall covering, allowing thewall board to expand and contract at will.

Still another purpose is to provide moulding and fastening devicecombined, the keeper section of the fastening device may be carried bythe studding, while a locking tongue to be received by the keeper, maybe carried by the moulding proper. v

A further purpose is to provide a moulding and fastenin device for wallboards, whereby the moul mg may be held in one position by means of asnap joint and disposed in its final position by providin a second snapjoint or connection, there y holding the moulding securely to thestudding and yet permitting the wall board to expand and contract.

A further purpose is to provide a moulding and fastening device adaptedfor interior and exterior corners, or for exterior wall coverings.

A still further purpose is to provide for a moulding and fasteningdevice which may be used for fastening wall board to the usualnow'extensively used plaster walls, the wall board covering in such aninstance being an imitation of tiling, making the wall boardparticularly adapted for painted rooms and the like.

It is to be understood that the particulars herein given are in no waylimitative, and

that while still keeping within the scope of the invention, any desiredmodification of details and proportions may be made in the constructionof the appliance according to circumstances.

The invention comprises further features and combination of parts to behereinafter set forth, shown in the drawingsand claimed.

Fi ure 14 is a sectional View showing a meta studding of an I beam type,illustrating the construction of moulding such as that shown in Figure8.

Referring to the drawings and more especially to Flgures 1, 2 and 3, 1identifies a studding and 2 are wall board sections. To

secure the wall board sections to the studding a moulding of sheet metal-is used. This moulding comprises a base member 3 and a cover member 4.The base member is made of sheet metal, suflicientl pliable to be rolledor otherwise formed as sliown in Figures 1, 2 and 3, but sufiicientlystiff and yieldable as to permit the base member to function ashereinafter attributed to the construction. The base member is formedfrom a single piece of such sheet metal bent at 5, and the portions 6beyond the bends are outwardly turned to form yielding flanges 7 whichare opposed and therefore provide a channel 8. The marginal edges of theflanges are overturned as shown at 9. The flanges have longitudinalgrooves 10 and 11. In other words the flanges are grooved at thesepoints providing seats.

The cover member of the moulding is constructed from sheet metal bent onitself as at 12 whereby the parts beyond the bends are extendedlaterally in the form as shown to provide a longitudinal tongue 13. Theopposed parts of the tongue are overlapped as shown at 14. This tonguehas aneck 15 and a rounded head 16, and when the wall board sections 2are arranged in position as in Figures 2 and 3 the cover member of themoulding may be disposed to overlie the wall board sections as shown andthe tongue snapped into the grooved seats 10 of the channel, holding thecover member of the moulding spaced from the wall board sections 2.While the cover member of the moulding is in this position, the wallboard sections may be painted or otherwise decorated, and such paintingmay be extended under the cover member of the moulding, the exterior ofthe cover member of the moulding being likewise painted, and after thepaint is dried, the cover member of the moulding maybe snapped into thesecond groove seats 11 of the channel, as shown in Figure 3, so thatthecover member of the moulding will retain the wall board sections inposition, and in such wise as to permit the wall board sections toexpand and contract without leaving exposed unpainted parts of the wallboard sections.

It is, obvious that at any time should it be necessary to remove any twoof the wall board sections, or any number of such sections, it is onlynecessary to withdraw the tongue of the cover member of the mouldingfrom the channel, allowing the wall board sections to be removed. Suchan advantage is very essential in the construction of partitions in oldhouses as well as new, so as to permit access to plumbing, gas pipingand other installation usually carried in the interior of the partition.

Referring to Figure 4 it will be noted that the studding 1 is the sameis in Figures 1 to 3, but the cover member 4' of the moulding isslightly modified in design, that is in ornagage, there being a firstposition as in Figure 2 and a second position as in Figure 3. Referringto igure 5 it will be noted that the channel and tongue construction issubstantially the same as in Figure 4, with the exception that there aretwo base members and two channels for the moulding, the basemembersabuttin at 21, the two se members being secure to the studding 1, whilethe cover member of the moulding is relatively wider than those inFigures 1 to 4 and overlie both channels, the exposed wall 22 of thecover member of the moulding being of a slightly different ornamentaldesign than those in Figures 1 to 4.

Referring to Fi ure 6 the construction of the base member 0 the mouldingis relatively wide so that the remote edge portions'of the base membermay overlie the sides of the studding 1 as shown at 23, the overlappmgparts to be secured by the nubs or projections 24. The channel 25 of thebase member in Figure 6 is the same as that in Figures 2 an 3.,

Referring to Figure 8 the base member of the moulding has the flanges 7b of the channel bent at.26,and the parts beyond the bends 26 areextended inwardly and have curved seats 27, there being only one setof'seats, so that in disposing the cover member of the moulding in itsinitial osition, the head 16 will engage the seats 2 and then when thecover member of'the moulding is disposed in its second position with itshead 16 beyond the inwardly turned parts which have the seats, theopposite edges of the inturned parts will engage behind the head andhold the cover member of the moulding in position, that is after thewall board sections 2 have been painted under the cover member of thedifferent formation or design. This moulding in Figure 9 is used on aplaster wall, the base member of the moulding being secured to the wallas at 28, and the wall board sections 29 in Figure 9 are supposed to bein imitation of tiling, so that the wall of a bath roofin will presentthe appearance of a tiled wa i O moulding, in construction, areidenticalwith the construction in Figures 1 to ,3, with the exceptionthat the cover and base members of the moulding arearranged foraninterior corner. a ,1

In Figures 12 and 13 the'construction of moulding is the same as in Fires 10 and 11 as well as in Figures 1 to 3mclusive, but

Referring to Figures 10and .11, it will be noted that the cover and basemembers of the showing the cover and base members of the mouldingadapted for exterior corners.

In Fi re 14 the wall boards 33- are disosed ad acent an I beam studding,there bemg bolts 34 enga ed in slots 35 and 36 of the base member 3 ofthe moulding, and the metal I beam 38, so as to hold the moulding basemember in position. The mouldin base member 37 is formed with opposedanges 39, which are bent at 40, and the portions beyond-the bends havecurved long 1tudinal seats 41 to receive the head 42 of the tongue 43 ofthe cover member 44 of the moulding, that is when the cover member 44 isfirst positioned. In other words the cover member 44 is first positionedwith the head 42 in the seats 41 until the wall board sections 33 arepainted under the cover member, then the'cover member is forced intoplace, its second position being against the wall board sections 33 withthe head 42 of the tongue beyond the edges of the curved seats 41, asshown in Figure 16. In this figure the cover member of the moulding isofslight- Ill) overlapping said sections, said molding having alongitudinal tongue to engage between the opposing yieldable sides ofthe channel, said yieldable sides having inwardly extending portions,provided with longitudinal cavities to receive a portion of theelongated tongue to retain the molding in its initial position, saidtongue having a longitudinal bead to assume a position beyond the edgesof the inwardly extended portions of the yieldable sides of the channel,thereby retainin g the molding in a second final osition.

2. In a device as set forth, the com ination with wall covering sectionsspaced causing an open seam to be formed, of a molding comprising a basesection and a cover section to close the open seam, said molding baseand cover sections having means connecting them whereby the moldingcover section may be disposed in an initinl position to permit paintinof the well cover sections under the mo ding cover section, said baseand molding cover sections including additional means to insure a secondfinal position of the cover section, to clamp the cover section inposition to prevent exposure of the unpainted portions oflthe wallcovering sections.

In testimony whereof he aflixes his signalo ture.
